Highly recommended. We spent a wonderful week at Montpelier Plantation in January of 2013. Incredible experience and we would go back in a heartbeat. Like almost all the resorts on Nevis this little dose of heaven is a converted sugar plantation with bungalow style rooms located high (690') up the hillside. The southerly views of the foliage and the sea are stunning. The feel is very intimate and serene. The attentive staff, who easily outnumber the rooms, were excellent across the board - friendly, genuine, and very good at their respective jobs.
The bars open when a guest arrives and close when the last one leaves. Each of the three restaurants has a unique feel, and the dining and all of them was excellent. I do not know how they accomplish this with a resort that has fewer than 35 guests at full capacity, but I am grateful for it.
The plantation's beach property is about 10 minutes away by car, and is lovely in its own right. We enjoyed a couple of afternoons there and also enjoyed exploring the other beaches on Nevis, most of which we had to ourselves.
Nevis is a very vertical island, and the foiliage is impressive. We really enjoyed the hike up Saddle Hill, and also took another hike inland into the rain forest that was good for a sweat but limited on scenery. We opted out, but one can hire a guide to hike to the peak of Mt. Nevis, which is a half day adventure at least.
